Not promoting slots or gambling, just remembering old Vegas.
It was buckets of nickels or quarters and the sound of coins pouring into the tray when my wife and I won. Not Vegas, but Reno and Tahoe for us.
I used to play the slots sometimes when I was working in Nevada quite a bit in the 80s. I’d wander around with my little bucket of coins, trying whatever machine caught my eye, and the sound of bells ringing and coins dropping into slot machine trays was almost constant. Too bad it was practically never the machine I happened to be playing.
About 15 years ago my wife and I went to Las Vegas and it was really odd to be in the slot room of a casino and not hear that noise. It was all paper tickets, and a lot of the fun was gone. I don’t think the machines even have handles to pull now. For all I know, they run on phone apps these days.
